Gravitation

7.1 Newton’s Law of Universal Gravitation Newton’s Law of Universal Gravitation states that: Every particle attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Consider two particles of masses m1 and m2 separated by a distance r. Each will exert a force F on the other, given by where F : gravitational force between the two particles. m1, m2 : masses of the...

Newton's Law of Universal Gravitation

Newton's Law of Universal Gravitation Gravity if one of the four fundamental forces in the universe. Though the fundamental principles of it eluded scientists until Sir Isaac Newton was able to mathematically describe it in 1687 (Eddington 93). Gravity plays a serious part in everyday actions as it keeps everything on the ground; without gravity everything would be immobile unless a force was applied (then it would move infinitely because there would be no force to stop it). Perhaps, the best...

Circular Motion and Gravitation

Circular Motion and Gravitation Circular motion is everywhere, from atoms to galaxies, from flagella to Ferris wheels. Two terms are frequently used to describe such motion. In general, we say that an object rotates when the axis of rotation lies within the body, and that it revolves when the axis is outside it. Thus, the Earth rotates on its axis and revolves about the Sun. When a body rotates on its axis, all the particles of the body revolve – that is, they move in circular paths about...

Universal Gravitation

Universal Gravitation Objectives * Compare and contrast gravitational force vectors as mass and distance are changed. (Explorations 1, 2, and 3) * Discover how changes in the distance between two objects affects the gravitational force between them. (Explorations 1, 2, and 3) * Describe how changes in the masses of two objects affects the gravitational force between them. (Explorations 1, 2, and 3) Description of Activity In this activity, you will explore how distance and mass...

Where Do Planets Come from

mighty planets are formed from cosmic dust. The red beans (dependent variable) were tested in the vacuum chamber with Earth’s gravitation pull and without the gravitation pull (independent variable) by pouring water into the chamber (buoyancy counteracts gravity). My hypothesis was that without the Earth’s gravitation pull, the particles would clump up; and with the gravitation pull, the particles would just remain the same. The Zhong 2 experimental results supported my hypothesis by showing that...

Newton's Laws of Universal Gravitation and Cooling

Newton’s Laws of Cooling & Universal Gravitation Law’s of Cooling: Newton's law of cooling is used measure the temperature change of an object of some temperature placed in a place of a different temperature. The law states that dT/dt= k(T-R) where T is the temperature of the object at time t, R is the temperature of the surrounding of the place (constant) and k is a constant of proportionality. This law states that the rate of change of temperature is proportional to the difference between...

Black Holes

until one huge black hole was created. Quasars, the bright area at the middle of galaxies that produces humongous quantities of energy, could possibly contain black holes. The intense black hole gravitation is strong enough to curve the time and space in its neighborhood. The intense gravitation causes a kind of a funnel consequence in that space time. This causes matters to be attracted gravitationally to it. It is supposed that the matter's atoms that enter the black holes are crushed into...

machines. In this wat some useful energy is wasted as heat energy. 2.)due to friction we have to exert more power in machines. 3.)due to friction noise also produced in machines Friction force and what does it state: newton’s law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Inter dependency between ATM locations and customer preferences

efficiency) of any ATM/store depends on its distance from the customer or gravity of attraction (Huff et al. 1963). The influence of any store/ATM decays exponentially as its distance from consumer increases Reilly’s Law of Retail Gravitation - Reilly's law of retail gravitation states that larger cities will have larger spheres of influence than smaller ones, meaning people travel farther to reach a larger city (Wagner et al. 1974). In our case we can consider ATMs to be cities and the ‘circle of influence’...

Ashford Eng 121 Final, Sun and Moon

from the sun. The moon acts as a mirror, reflecting the sun’s light, which gives it the appearance of illumination. Scientists have always known the sun and moon play some part in the tides. However, it was not until Isaac Newton’s theory of gravitation in 1687 that the phenomenon could be explained. (The Heavens, 1992). Since then, it has been discovered that the moon is responsible for about 54 percent of the tidal forces, while the sun accounts for about 46 percent. The moon’s gravitational...
